🛑 Breaking changes 🛑

• cmd/mdatagen: Make stability.level a required field for metrics (#14070)

• cmd/mdatagen: Replace optional field with requirement_level field for attributes in metadata schema (#13913)
  The optional boolean field for attributes has been replaced with a requirement_level field that accepts enum values: required, conditionally_required, recommended, or opt_in.

  • required: attribute is always included and cannot be excluded
  • conditionally_required: attribute is included by default when certain conditions are met (replaces optional: true)
  • recommended: attribute is included by default but can be disabled via configuration (replaces optional: false)
  • opt_in: attribute is not included unless explicitly enabled in user config
    When requirement_level is not specified, it defaults to recommended.

• pdata/pprofile: Remove deprecated PutAttribute helper method (#14082)

• pdata/pprofile: Remove deprecated PutLocation helper method (#14082)

💡 Enhancements 💡

• all: Add FIPS and non-FIPS implementations for allowed TLS curves (#13990)
• cmd/builder: Set CGO_ENABLED=0 by default, add the cgo_enabled configuration to enable it. (#10028)
• pkg/config/configgrpc: Errors of type status.Status returned from an Authenticator extension are being propagated as is to the upstream client. (#14005)
• pkg/config/configoptional: Adds new configoptional.AddEnabledField feature gate that allows users to explicitly disable a configoptional.Optional through a new enabled field. (#14021)
• pkg/exporterhelper: Replace usage of gogo proto for persistent queue metadata (#14079)
• pkg/pdata: Remove usage of gogo proto and generate the structs with pdatagen (#14078)

🧰 Bug fixes 🧰

• exporter/debug: add queue configuration (#14101)

API Changelog

🛑 Breaking changes 🛑

• all: Change type of configgrpc.ClientConfig.Headers, confighttp.ClientConfig.Headers, and confighttp.ServerConfig.ResponseHeaders (#13930)
  configopaque.MapList is a new alternative to map[string]configopaque.String which can unmarshal
  both maps and lists of name/value pairs.

  For example, if headers is a field of type configopaque.MapList,
  then the following YAML configs will unmarshal to the same thing:

  headers:
    "foo": "bar"
  
  headers:
  - name: "foo"
    value: "bar"

• pdata/pprofile: Update SetFunction to return the function's ID rather than update the Line (#14016, #14032)

• pdata/pprofile: Update SetLink to return the link's ID rather than update the Sample (#14016, #14031)

• pdata/pprofile: Update SetMapping to return the mapping's ID rather than update the Location (#14016, #14030)

• pkg/otelcol: Require a telemetry factory to be injected through otelcol.Factories (#4970)
  otelcol.Factories now has a required Telemetry field,
  which contains the telemetry factory to be used by the service.
  Set it to otelconftelemetry.NewFactory() for the existing behavior.

• pkg/pdata: Remove unused generated code from pprofile (#14073)
  Experimental package, ok to break since not used.

💡 Enhancements 💡

• pdata/pprofile: Introduce SetStack method (#14007)
• pdata/xpdata: Add high-level Entity API for managing entities attached to resources (#14042)
  Introduces Entity, EntitySlice, and EntityAttributeMap types that provide a user-friendly interface
  for working with resource entities. The new API ensures consistency between entity and resource attributes
  by sharing the underlying attribute map, and prevents attribute conflicts between entities. This API may
  eventually replace the generated protobuf-based API for better usability.

🧰 Bug fixes 🧰

• cmd/mdatagen: Fix mdatagen generated_metrics for connectors (#12402)
